DEVICE FOR APPLYING REVENUE STAMPS TO PACKAGE-WRAPPING MATERIAL TO PREPARE II FOR USE IN PACKAGING MACHINES.

Application filed August 12, 1926. Serial'No. 128,727.

This invention relates to a device for applying revenue stampsto package wrapping outspread condition in order to avoid the dificulties heretofore encountered in makingrevenue stamps stick to more or less irregularly shaped wrapped packages. plvith this and other objects not specifically mentioned in View, the inventionconsists incertain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended. 4

In the accompanying drawings, in which like characters of reference indicate the same or like parts, Fig. 1 is a side elevation of a device constructed in accordance with the invention; Fig. Qis a plan view of the same; Fig. 3 is an end elevation of the same; Figs. 1 and are end views of the stamp feed in its two extreme positions, as seen jflOlll'tllt line 55 in Fig. 1; and Fig. 6 is a side view of the wrapper aligning and ejecting devices.

In carrying the invention into effect, there is provided a source. of wrapper material supply. a source of revenue stamp supply, mechanism for assembling in outspread condition wrapping material and stamps drawn from said sources of supply, and means for causing said out-spread and assembled wrapping material and stamps to stick together preparatory to use of said wrapping material and stamps in packaging machines. In the; best constructions contemplated, the source of wrapping material supply includes a magazine for individual wrappers and means for successively delivering wrappers therefrom to said mechanism; the-s0urce of revenue stamp supply includes a magazine for individual stamps and means for successively delivering stamps therefrom to said mechanism; and the means for causing said outspre'ad and assembled wrapping material and stamps to stick together includes a pasteapplying device coactive with said mechanism between said sources of supply. These parts may be widely varied inv construction within the scope of the claims, for the particular structure selected to illustrate the invention is but one of many possible concrete embodiments of the same; The invention therefore is not tobe restricted to the precise details of the structure shown and"v described.

Referring to the drawings, Figs. 1 to 3, the device is mounted on the frame of the machine whichconsists of a rectangular casting 7 having an end upright 8 and side uprights 9 and 10. The wrapper magazine 11, which is stationary, has end plates 12 by means of which it is attached to' the uprights 8 of the frame. The stack of wrappers 13 in the magazine rests on a rollerv 14 whose shaft 15 has a sprocket 16 driven by a chain 17 from a sprocket 18 of a drive shaft 19. The shaft.

15 of the roller 14, by means of a. gear 2 intermediate gear 2]., and gear 22, drives the pull-out rollers 23 which are supported between plates 24, the, latter being pivoted on the shaft 15 and adjustably held stationary by screws 25. The plates 24 also carry an adjustable rod 26' upon which are mounted two guides 27 and an intermediate guide 28 for the emerging, wrapper. The rollers 23,

by the aid of the guides 27 and 28, deliver the wrapper 13 to the endless conveyor 29 running over sprockets 30 and '31, the shaft 32 of the former being adjustable in the frame 7, while the shaft 33 of the latter is fixed.

The endless conveyor 29, atequidistant intervals'. is provided with prongs 34 which propel the wrappers at each step of the conveyor. conveyor is derived from a ratchet wheel '35 which is actuated by a pawl 36 carried on the upper arm of a bellcrank 37 andheld against the ratchet by aspring 38. The

The intermittent motion of the frame 7.

ratchet 35 is fixedly, and the bellcrank 37 is loosely, mounted on the sprocket shaft 33, and the lower arm of the bellcrank 37 is connected by a rod 39 with an eccentric pin 40 on a disc 41 mounted on the drive shaft 19. While being propelled by the conveyor 29, the wrappers rest on the supporting strips 42 and 43, the side strips 43 being joined to the center strip 42 by cross strips 44, and the center strip 42 being supported by a rod 45 from a cross bar 46 attached to the frame 7. The opposite edges of the wrapper slide on end rails 47 supported by brackets 48 fastened to the cross bar 46 and 1 After being deposited on the conveyor, the wrapper 13 is pushed by the aligning strip 49 against the stop plate 50 attached tothe end rail 47 (Fig. 3). The aligning strip 49 (Figs; 2, 3 and is connected by a bar 51 to the upper end of a double bellcrank 52 fulc-rumed in a projection 53 of the frame 7, and actuated by a rod attached to an eccentric 55 mounted on a shaft 58 which carries a sprocket 57 driven by a. chain 58 from a sprocket 59 on a shaft 60. The

shafts-56 and (SO are carried by bearings 61 and 62, respectively, mounted on the frame 7, the shaft having a spiral gear 63 meshmg with a gear 64 on a vertical shaft 65.

I The shaft 65 is supported by bearings 66 and 67, the former of which is attached to the frame 7, and the latter to the upright 9. The shaft 65 is driven by a bevel gear 68 meshing with a gear 69 on the drive shaft 19.

As the wrapper 13 passes under the stamp magazine 70, a stamp 71 is deposited on its edge which has previously been supplied with paste, the stamp being smoothed down and sealed by a brush 72 attached by an arm 73 to the frame of the magazine 70. The stamp magazine has a laterally projecting pin 74 by means of which it is suspended, by a lever 75, from. a shaft 7 6 supported in .the uprights 9 and 10, and has a vertical slide 77 movable in a guide 78 fastened to the upright 9.

The shaft 76 is rocked by means of a crank 79 connected by a rod 80 to an eccentric 81 on the drive shaft 19, thereby giving to'the stamp magazine a periodic up-anddown motion. The stamp magazine (Figs. 4 and 5) has horizontal side brackets 82 which carry shafts 83 and 84 upon which are mounted levers 85 engaging the stamps 71. On one end of the shaft 83 is mounted a lever 86 carrying a pin 87 engaging a slot in a lever 88 clamped to the shaft 84 on which is also mounted an arm 89 having its free end shaped in hook-fashion, the hook portion engaging with a stop 90 attached to the frame 7 when the magazine slide is in its lowermost position. The pin 87 is pulled upwards against a stop 91 mounted on the magazine frame by a spring 92 attached to the slide 77, thereby pressing the free ends of the levers 85 against the edges ofthe stamps 71.

As the wrapper 13 arrives below the stamp magazine 70, the latter comes down on it, the magazine thereby being held sta-v the levers 85 and releasing the stamps, the

lowermost. of which adheresto the wrapper which is held down by suction furnished by a vacuum pump 93 through a hose connection 94 and suction head 95 in one of the rails 47, while the magazine moves up. As soon as the arm 89 leaves the stop 90, the levers 85 re-engage the stampsv and move all except the lower most one up in the magazine until the rear side bracket 82 again'engages the stop 91, whereupon magazine and slide move up together, the wrapper being meanwhile held down by the suction. By the relative motion'between the magazine and its sllde,'the bulk of the stamps is separated from those below the levers 85, thus releasing the weight from the bottom stamps and making the action of the stamp discharge independent of the height of the stack. The suction pump 93 is attached to the frame 7 r and is driven by an eccentric 96 mounte on the drive shaft 19. I The pasting device consists of the stationary paste reservoir 97 having the rotating paste drum 98, and of the swinging paste 7 transfer 99. The paste reservoir 97 is detachably mounted on a bracket 100 attached to the upright 9. It is provided with bearings for the shaft 101 of the paste drum 98,

and also carries a scraper 102 which removes the surplus paste from the drum. The drum shaft 101 has a sprocket 103 which is driven by a chain 104 from a sprocket 105 on a shaft 106 journaled in a bearing 107 attached to the frame 7. The shaft 106 is driven by a bevel gear 108 meshing with a bevel gear 109 on a cam shaft 110. The cam shaft 110 is journaled in the frame 7 and has a sprocket 111 which is driven by a chain 112 from a sprocket 113 on the drive shaft 19.

The paste transfer 99 is mounted on a shaft l JU meshing with a rack 117 mounted'on a vertical slide 118 movable'in a guide 119 attached,

to the frame 7. The lower end of the-slide 1.18 is provided with a lug 120-which, by a link 121, is connected to the free end of a cam lever 122, the latter being fulcrumed at 123 on the frame 7 and carrying the roller 124; which is kept in engagementvitlr a cam 125 on the shaft 110by means of a spring 126 attached tothe frame 7. As the lever 122 is moved up and down by the cam 125, the rack 117 turns the gear 116 back and forth, thereby transferring paste from the drum 98 to the wrapper 13 on the rail 47, I as shown by dotted lines in Fig. 3.

lVhile beingcarried from the magazine 11 pastthe pasting device 97, stamp magazine 70, and stamp sealing brush 72, thewrapper 13 is guided by a wire 127'stretch'ed between brackets 128. and 129' attached to the frame 7. The attachment to the bracket 12S made adjustable by means of a screw 130, so that. the tension of the wire 1127 can be regulated from time to' time. Vhile being pasted, the wrapper is held in place by a finger 131 attached to a bcllcrank lever 132 'flllCllllHCd' in a bracket fastenedto the upright 10 and carrying a roller 13% held in engagement with a cam 135 on the shaft 110 by a spring Having passed the brush 72, the stamped wrapper is guided around, a. drum 137 mounted between the sprockets 31 on the shaft and; around edge guides 138 a-ttached to the rails 47, by the guard strip 139 attached to the frame 7, being held in contact with the drumby a tape 14:0 hung from the stamp magazine supporting shaft 76 and kept in proper tension by the weight 141 attached to its lever end,

On its return passage, the wrapper is sup-. ported by the center rail 142 and by the side guides 143- hung by the bridge pieces 144 from the center rail. The latter is'supported at one end-by a bracket 145 attached to the frame 7, and at the other end by a rod 146,

adjustably mounted on a cross bar 147 resting on the bases of the bearings 61 and 62-. Upon reaching the end of its return path, the stamped wrapper is held by a stop 1'48 adjustably supported on a plate 1&9 mounted on the rod 1413, and is then delivered sidewise to a drum 150 on which it is held by a roller 151, The delivering pusher 152 is a partof a slide 153 supported on a guide 154 and connected by a link 155 with the lower arm of the double bellcranli52 before. referred to. The drum 150 is mounted on a shaft 60 supported in bearingsfiQ to which are fastened forked brackets 1-56 carrying the roller 151. From the drum150, the

stamped wrapper passes into the folding demovements of said support and said magato withdraw said stamp from said magazine, said relative movements belng .efiected by moving said magazine only. 1
